GUS-QS8A-03-1543-DB Description

The GUS-QS8A-03-1543-DB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. It features a 154KΩ resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, this network offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it ideal for precision analog and digital circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance reliability in high-voltage environments.

GUS-QS8A-03-1543-DB Features

• Thin Film Technology: Delivers superior accuracy, low noise, and long-term stability.
• High Power Density: 0.75W total power in a miniature 4.9mm x 6.02mm footprint (1.47mm height).
• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR for critical applications.
• Robust Construction: QSOP package with 0.64mm terminal pitch ensures mechanical durability and ease of soldering.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Isolated Design (ISOL): Each resistor is electrically independent, reducing crosstalk in multi-channel systems.
